Features:New sample engine applied to both plugged and unpluggedABU is designed from the ground up to be the most versatile bass virtual instrument available today with a new level of expressiveness. ABU not only performs as an extraordinary acoustic instrument by playback partially from mic samples, but also as an electric instrument by playback partially from DI samples, creating a more dynamic and subtle playing experience. Furthermore, users can mix and process Mics and DI separately to get a variety of sound.

Multiple stereo and mono modesABU uses more mics to record every detail of upright bass from neck, body and ambience and provides 2 stereo modes and 2 mono modes on mix interface. Users can adjust volumes of mics and width to get more options in stereo mode, in which ABU has rich expressiveness even for solo. For mono modes, ABU can play an important role of middle-low end in a band steadily.
